Dave recently used Golang for a project he was working on, and today he shares his experience of interfaces and design patterns in the language. We kick off the show by talking about the Gang of Four, where Mike reveals what we have long suspected – he’s not a real developer after all! We then talk about how Go is different from other languages in that you have to explicitly define the interface and then you have a file with an interface in it. This means that when you write the code that implements the interface, you don’t explicitly say what it’s doing. It's all a big secret!
